EXTENSIQN TRUNK.

Application filed larch as, 1927, Serial No. 178,744

This invention relates to trunks of the type carried at the rear of motor cars for the' transportation of luggage, tools, etc., and my main object is to form the trunk with an extensible portion, for .use when greater capacity is desired.

. 'A further object of the invention isto design the novel extension with a telescoping action, whereby to occupy a minimum Anotherobj ect of the invention is' to construct the: novel extension with fastening Figure 1 is an elevationpartly brokena'way'of the improved trunk, as viewed from the rear of the motor car or other vehicle 'on which it may be installed;

is hinged at 14 from the frontwall, and is formed with beaded reinforcements 13 to fit walls 11 for better alinement with the latter. The extension involves but'the side walls e and bottomof the trunk, and when con- .45

sidered with the latter, comprises an intermediate section 15 and a rear section 16, the.

intermediate section-'beingadapted to telescope into the trunk, andthe rear section into the intermediate section. When the as sembly is telescoped, the rear wall 16 of the sections 16 forms a closure for the rear end of the trunk, with which the lid may join as indicated in Figure 5, customary locking Referring specifically to the drawings, denotes the front wall of the trunk, 11 the The lid-13' doubled flanges 11 formed from .the sidedevices 17 completing the closure whereby to hold the rear wall in place and give the trunk the ordinary, short appearance.

In extending the trunk, the latter and the WILL FREEMAN, or has extension have cooperating guide elements to maintain the alinementof the extension sections with the trunk. Thus, the upper edges of the'sides 15 and 16 of the respective sections are formed with angular flange lengths .15 and 16, respectively, whichseat within each other and are relatively slidable; and the side walls 11 of the trunk carry on their inner sides similar lengths 11-.rein-.

forced by suitable webs 11"to receive and guide the lengths-15. At the bottom, the trunk bottom 12 as well as the respective extension bottoms 15 and 16 are given a common angular formation 18 to provide the necessary guidance along the bottom of the assembly. The extension section 15 is only designed to emerge about half-wayfrom thetrunk when fullyextended; and so with the section 16 .relative to the section 15. Substantial bearings are thus provided for the sections as against dlStOItlOIl' or weakening from the weight or pressure of the contents.

The section'lG-operates the section 15 by means of pins 19 carried by the sides 16 and passing lnto horizontal slots 20 in'the sides 15. The length of the slots is, of course,

gaged to secure the proper distance of travel by the section 15 in either direction; and the frontal edges of the sides 15 are formed with outward lugs 21 designed to abut in-.

Ward stops 22 formed from the rear edges of the side walls 11 of the'trunk in case such sides creep in a rearward direction from vibration, so that the section 15 cannot become separated fromthe trunk.

A top and bottom connection between the section 16 and the front wall 10 of the trunk is-formed by aset of foldin eachwa-ll. These are secured by loose rivets 23 to the parts connected, and have'a locking pin 24 and seating notch 25 therefor to prevent complete'unfolding when the section 16 has been fully extended. Thelin'ks links 22, along 'will thus fold readily when the section is I again closed, and without a tendency to bind. Qwing to the intimate grouping and overlapping of the sections, the intermediate one need not have a medial bottom portion as the rear section always overlaps the trunk bottom. 'Hence, no opening would be created in the bottom. ofthe extension by reducing the bottom of the intermediate section to the extent indicated at 26, whereby metal may be economized.

The space indicated at 27 in Figure 2 is' shown high for purposes of illustration, and 1 to suggest that room must beleft in the bottom of thetrunk for the heads of the bolts usually employed to fasten the trunk to the carrier or shelf which supports it.

The improved trunk is thus a structure of "simple design'an'd ample strength whether in normal. or extended position. This is necessary when it is desired to support the spare tire v28 irom the trunk as shown. Having the rearmost position, the spare tire supplements or even supplants the bumper for protective purposes; also, bumper is already carried, the spare tire is positioned where the bumper is notin its way.

. ile 'thefextended trunk may on ac- I count of the usually open state ofits' extension' be covered with a hood in the event of inclement weather; I have thought it preferable to provide a special cover 29 for the extension. As indicated more clearly in Figure 1, this cover is normally concealed Within the trunk cover 13 by hin ing at the 'rear end, as indicated-at 30, an

retaining its front end in a spring clip 31 depending from the cover 13. Thus, when the trunk is i a cover for the extensible section hinged extended the extension cover 29 may be swung outv and rested upon the extension as indicated by finelydotted lines in Figure 4. I i

I claim v 1. An extensible auto trunk comprising a main section, a-hinged' cover therefor, 21 section extensible from the main section, and

from the free end of ,the main cover and foldable within the latter.

2. An extensible auto trunk comprising a main section with its rear end open, and a plurality of secondary sections rearwardly [extensible from the open end of the main Where Y a section, such secondary sections being in a telescopic series with the main section.

3. An extensible auto trunk comprising a main section with its rear end open, and a plurality of secondary sections rearwardly extensible from the open end of the main section, such-secondary sections being in a series telescopically diminishing from the main section.

4. An extens1ble auto trunk comprising a mam section with one end open, a cover for said main section, a plurality of secondary within the latter, and a spare tire carnier mounted on the end wall of said extensible section and movable therewith. p

6. An extensible auto trunk comprising a main section-with itsrear end open, and a plurality of secondary sections rearwardly extensible from the open end of the main section, such secondary sections being in a telescopic series with the main section, the rear most section of said secondary sections havinga vertical wall adapted to cover the rear open end of said main section.

7. An extensible auto trunk comprising a main section having its rear end open, a, movable section havlng a rearwall to cover said 'openend, said movable'section being ada ted to form an extension of said main section, a hinged cover for said main section and a hinged cover for said movable section, said last cover being connected to said first cover and adapted to fold therebeneath when inoperative.

In testimony whereof I afiix my signature.
